The splenius cervicis (/ ˈ s p l iː n i ə s s ər ˈ v aɪ s ɪ s /) (also known as the splenius colli, /-ˈ k ɒ l aɪ /) is a muscle in the back of the neck.It arises by a narrow tendinous band from the spinous processes of the third to the sixth thoracic vertebrae; it is inserted, by tendinous fasciculi, into the posterior tubercles of the transverse processes of the upper two or three ...
The splenius muscles are: Splenius capitis muscle; Splenius cervicis muscle; Their origins are in the upper thoracic and lower cervical spinous processes. Their actions are to extend and ipsilaterally rotate the head and neck.
The splenius capitis (/ ˈ s p l iː n i ə s ˈ k æ p ɪ t ɪ s /) (from Greek splēníon 'bandage' and Latin caput 'head' [1] [2]) is a broad, straplike muscle in the back of the neck. It pulls on the base of the skull from the vertebrae in the neck and upper thorax .
The semispinalis capitis (complexus) is situated at the upper and back part of the neck, deep to the splenius muscles, and medial to the longissimus cervicis and longissimus capitis. It arises by a series of tendons from the tips of the transverse processes of the upper six or seven thoracic and the seventh cervical vertebrae , and from the ...
Lower cervical extensors: splenius cervicis, semispinalis cervicis, longissimus cervicis; Upper cervical (capital) flexors: longus capitis, Rectus capitis anterior, Suprahyoid muscles; Massage, to loosen adhesive fibrotic tethering of the posterior neck and upper trapezius muscles. [35]
It gives off muscular branches to the Semispinalis capitis, and occasionally a twig to the back of the auricula. The lateral branch (ramus lateralis; external branch) supplies filaments to the Splenius, Longissimus capitis, and Semispinalis capitis, and is often joined by the corresponding branch of the third cervical.
semispinalis cervicis; semispinalis capitis; The multifidus muscle, and spans 2-4 vertebral segments The rotatores muscles, lie beneath the multifidus, and spans 1-2 vertebral segments rotatores cervicis; rotatores thoracis; rotatores lumborum
spinalis cervicis originates from the spinous process of T2-C6 and inserts in the spinous process of C4-C2. spinalis capitis is an inconstant muscle fiber that runs from the cervical and upper thoracic and then inserts in the external occipital protuberance.
